INSULATOBi Specification 0 Application tiled February To all whom it mayconcern:

lie it known that l, Funnnmon Josnru lhun, a citizen of the UnitedStates, residing at 'est Lebanon, in the county of Varren and State ofIndiana have invented certain new and useful Improvements In Insulators;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertams to make and use the same.

My invention relates to new and useful improvements in insulatorattachments and more particularly to that class adapted to telephone,telegraph or electric wires, an my to provide means for securing theinsulating devices to the usual form of cross arm carried at the upperend of support' poles.

A further object is to prev] e means whereby the insulating blocks maybe read ily attached to the wires.

.-\-still further object is to provide means for clamping the parts ofthe insulating device around the wires.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed outin the claims I Inthe accom anying drawingswhich are i this application, Figure 1 is} a side elevation of myimproved insulater and securing device therefor. Fig.2 is

and to obviate this result, I provide a metal standard the lower end ofwhich is in :r-vduted through an opening 3 in the cross arm, thedownward movement of the stand ard being limited by means of a conicalcollar 4-, while the extreme lower end of the standard is threaded toreceive a nut 5, by which means the standard is secured to the crossarm.

That portion of the standard above the collar 4 is divided into twosections 6 and 7, the section 6 being integral with the standard whilethe section I is pivolally secured ing a pivot, pin 8 through thestandard 2 and the extreme lower end of the section 7. The sections 6and T are provided adjacent their upper ends with semicircular clampingmembers 9 and 10. respectively, said members having re ering cavities 11and 12, respectively w ich are adapted to receive insulating blocks 13and 14, res t-ively, th block 13 havin" a rib 15 exten ng longitudinallythereof, while each edge of the block 14 is provided with a flange 16adapted to extend at opposite sides of the rib l5 and clamp the wire 17over the curved fare of, the rib, said rib having a depression l8 atitslongitudinal center to 'iorm a seat for the wire, the inner faces ofthefianges 16 being rounded, thus obviating the pumihilit of cutting orinjuring the and at the same t-ime'grip the same with-sufiicient tensionto revent'lo "tudinal movement lqf the-wire etweenthe locks. ;Theextremeupper ends of the sections 6 d fil are secured together by meansof a mgn atits lower end to the standard by introducextend wheiifturlied I e h lnmp ngl olt 22,

made much smaller than if constructed of wood, thereby requiring asmaller openinf; through the cross arm to receive the slant ard, while,by forming the collar -1 integral with the standard and providing atapered upper surface therefor. water, or the like, will be preventedfrom entering the opening 3 in the cross arm when said collar is firmlyclamped in position on the arm.

In securing the wire to the standards the two sections of the standardsare separated and the wire placed in position between the insulatii'igblocks. after which the section T is swung upwardly and the block 14moved into engagement with the block 13, when the clamping bolt '22 isswung downwardly between the cars 24 and the wire firml clamped betweenthe blocks hv turning the wing-nut onto the clamping bolt, and .b v proriding a convex surface or rib on the block 13 and flanges on the fareof the block 14 between which the rib the wire will be crilnped over therill and securely held against longitudinal movement, thus holdin thewire taut between each set of stand ar ds. It will thus be seen that Ihave provided a means for securing insulators to so porting arms whereinthe insulator may quickly secured to or removed from the se curingdevice and it'- will likewise be seen that by providing the clampingmechanism-as shown, the wire to which the insulator is attached. may heheld taut along the line of posts from which said wires are 5115 l fl'What- I claim is:

1. The herein described insulating device, comprising the combinationwith an arm; of a standard adapted to be secured to said arm, a collaron said standard, the upper face of which is in d, sections above saidstandard, one of w ich is integral with the standard and the oppositesection pivotally secured thereto, cla ing members adjacent the it perends of sect-ions hat cavities t emin, insulating blocks adap d to.

enter the cavities and means atthc 11 per the sections of the insulatorv ends of the'sections of the standard nip an insulating device of {theYclnss3iiescribed comprising the a standard having sections at one endthereof, one of which sections is integral with the standard and theother section hinged there to, clamping members adjacent the upper endsof said sections having cavities on their inner faces. cars at the upperends of said sections, a clamping bolt. pivoted to the ears on onesection and adapted to extend between the ears on the opposite section,shoulders on the pivoted section and a wingnnt for said bolt; ado ted toclam the ivoted section against tie fixed section; 0 an insulator formedin two sections, one section having a rib and a wire receiving grooveextending transversely of said rib and flanges on the opposite sectionof the insulator adapted to cooperate with the rib on thefirst-mentioned section of the insulator and ela m a wire passingbetween said sections.

3. u an insulator attachment, the combination with a standard havi w oneof its ends threaded. a collar intcgra with said standard and having atapered upper face, sections at the 1: per end of said standard, one ofwhich is h xed with the standard and the opposite section pivoted to thestandard, clamping members adjacentthe up or ends of said sectionshaving cavities in meet ing faces thereof, cars at the upper ends ofsaid sections, one set of said ears having shoulders, a clamping bolt;pivoted between one set of cars and adapted to extend "between theopposite ears, a nut; on the free end of said bolt adapted to hold thepivoted section in juxtaposition to the fixed section, said nutextending below and 0 :mid shoulders when the sections their closedpositions; of an insulator fanned in two sections and adapted to fit: inthe cavities in the elm-aging members and be held together there y andmeans to prevent longitudinal movement of a wire saidinsulator-sections.
